. Bulletin of the Department of Agriculture. Agriculture; Agriculture -- United States. TIMBER STORAGE IN THE EASTERN AND SOUTHERN STATES. 29 beyond the eaves (fig. 32). Very few sheds are equipped with gut- ters (fig. 31), and the drip during rains may run back along the projecting pieces well into the center of the piles. When once wetted the close piles will retain this moisture for long periods, during which a serious outbreak of decay may be initiated. A few cases of severe outbreaks in retail lumber sheds will be de- scribed and illustrated later. YARDS. On account of ver}^ limited storage space, nearly all retail yards fail to observe the proper spacing of lumber to insure ample ventila- tion. The general tendency is to pile altogether too close to the ground for safety, and in many instances the lumber is not spaced as well in the piles as. it should be (fig. 33). The principal danger lies in the foundations, which are very often seriously infected with rot (fig. 34) or are not adequatel}^ constructed to insure proper venti- lation. The danger in allowing lumber to come in contact with the soil is evident in figure 35. As the ques- tion of foundations in mill yards was dis- cussed' in considerable detail earlier in this publication and since the fundamental con- siderations apply with equal force to retail yards, only certain features which serve to connect these fundamentals with the direct problems of the retail yard will be added here. Many retail lumber yards use solid or latticed foundations of built-up plank running parallel to the alleys (figs. 36 and 37) ; others resort to wood blocking for the support of the skids. The use of concrete is very limited, but has giA^en complete satisfaction wherever introduced. It is usually laid down as solid foundations parallel to the alleys. In one yard at Birmingham, Ala., the founda- tions were 8 to 10 inches high, 6 inches thick at the top, and placed in triple parallel rows spaced 7 feet apart (fig. 38). T
